How XBIT iv/hv history Data Feeds Strategy Selection
Strategy selection on XBiotech Inc. options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 35.9% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the iv/hv history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.
How to read the XBIT IV vs HV chart
The dual-line chart above tracks ATM implied volatility (forward-looking, what the chain is pricing) against 20-day realized historical volatility (backward-looking, what actually happened). ATM IV currently prints at 35.9%, 2.9% IV rank, against 21.2% realized over the trailing 20 trading days. Implied is pricing above realized by 14.7 vol points, the typical variance-risk-premium positive state in which premium sellers earn the gap. Persistent IV-above-HV is the variance-risk-premium-positive state typical of equity markets; persistent IV-below-HV is rare and usually marks underpriced vol that often expands.
XBIT IV/HV regimes and trade selection
XBIT sits in the bottom quartile of its 1-year IV range. Low-IV-rank regimes favor premium-buying or long-vol structures - long calls/puts, debit spreads, calendar spreads, long straddles. The risk: low rank can persist for months while theta decay eats premium-buyers alive without a vol-expansion catalyst.
Using XBIT vol history alongside the term structure
The IV/HV gap on this page captures the level of premium; the term-structure slope on the volatility page captures its shape across expirations. Contango (positive slope 3.248) is the resting state - longer-dated IV trades above near-dated IV because long-dated cycles include uncertain macro states. Pair the rank read with the slope read with the event calendar to choose the right tenor for the structure.
XBIT IV/HV signal in volatility-cycle context
Equity-vol cycles tend to compress and expand on multi-month timeframes: a typical sequence runs low-IV-rank consolidation (months of flat tape, decaying premium) into a vol-expansion catalyst (earnings miss, macro shock, regime change) into elevated-IV-rank stress (premiums fat, dispersion high) back to mean-reverting compression. XBIT's current 2.9% IV rank places the ticker in the compression phase of that cycle. Compression phases are profitable for theta-harvesting structures but tend to end with abrupt vol-expansion regimes that hit short-vol books fast. The ratio of HV-20 (21.2%) to HV-60 (27.3%) gives a second cycle indicator: when 20-day exceeds 60-day, recent realization is running hotter than the trailing-quarter average - typically a sign that recent days have already started expanding vol regardless of where IV rank prints. Use the time series above to spot inflection points: meaningful IV/HV gap closures and openings tend to precede regime shifts by a few sessions.

Frequently asked XBIT iv/hv history questions
- Is XBIT options pricing rich or cheap right now?
- As of May 29, 2026, XBiotech Inc. (XBIT) ATM IV is 35.9% against 20-day realized volatility of 21.2%. IV rank is 2.9%. XBIT options are pricing in more volatility than the stock has recently realized: a positive variance risk premium worth 14.7 vol points.
- What is the XBIT variance risk premium?
- The variance risk premium is the persistent gap between implied and subsequently realized volatility. In equity markets it averages positive because option sellers demand compensation for bearing variance shocks. XBIT is currently priced consistently with this premium, which is one input to whether short-vol or long-vol structures carry their typical edge.
- What does XBIT IV rank mean for strategy selection?
- IV rank normalizes the current ATM IV to its 1-year range: 0% is the low, 100% is the high. XBIT's current rank of 2.9% signals where current pricing sits in its own 1-year history. High-rank regimes typically favor premium-selling structures (credit spreads, condors, covered calls); low-rank regimes typically favor premium-buying or long-volatility structures.
